This invention relates toa foldingbox, preferably madeof corrugated paperboard, and adapted particularly for containing stacks of post card sheets, or other paper sheets of value, Which are to be shipped by cxpress'or through the mails.- These sheets are usually counted before being boxed for shipment, and in case shortage is found When the box arrives at` its destinatiomyit becomes important to know whether the shortage is due to a miscount at the sending office, or whether the box has `been tampered with and sheets removed while in transit.

The purpose of my invention is to provide a light and strong box in which such stacks of post card sheets, may be transported, which cannot be opened except by mutilation of the box, and Which is provided with a sealing strip so aiiixed to the box that any attempt to remove the strip and replace it with another will be apparent upon inspection of the box. Thus, if the boxarrives atv its destination unbroken and with the original sealing strip in. perfect condition, it

l may be opened and if there happens to be a shortage in the number of card' sheets in the box,it Will be evident that there has been amis-countof the sheets in packing the box. 0n the other hand, if the original seal is not in place and in perfect condition, the receiver of the box will know that an attempt h'as been madeto tamper with the box and he may refuse to receive orv open it, and thus he Will not be charged with any shortage that may afterwards be found.

In the accompanying drawings, Fig. 1 is a perspective view of' a box mad in accordance with my invention; Y Fig. 2 'is a transversesection on the line 40 g2-f2 of Fig. 1;

Fig. 4 is a section through a corner of Q the box, on the line-4 4 of Fig. 1; Fig. 5 is a perspective view of a blank from lwhich the box is made, partly folded, andshowing also indotted lines a package to be enclosed by the box, and in full lines, a portion of the board to which the top portions are sealed when the box is closed;

.side flaps along formed by slottirg cated at l in Fig.

come securely affixed to the board Fig. 6 is a perspective View of oneend of the box, With the sealing strip extending over the end Hap.

Referring first to Fig. 5 of the drawings, the'blank from which the box is made com- 55 prises a rectangular base 1, end flaps 2, side flaps V3 of approximately the same length as the base, said end and side flaps being connected to the` base alongA creasedflines .a and respectively. Cover portions 4 60 each approximately equalfin Width to half the Width of the base, are connected to the y creased lines c, and each cover portion has end flaps 5 to which are connected cornerfl'aps 6. `The flaps 6 are 65,

the blankk inwardly from its ends, as shown at l7, to the pointswhere the creased lines a and b meet and thence along the creased lilies a to the creased lines e, as indicated at 8. 70 In folding theA blank, the corner flaps Gare turned at right angles to lthe, flaps 5, and thelatter are then turned at right angles to thecover portions 4', and the latter portions are turned at rightll angles yto the sides 3, as shown at the lieft side of Fig. 5. By then turning the sides 3"at right angles to the base, the edges 4 vof the cover portionsand the edges 5a of the flaps 5 will meet along the longitudinal 'center line of 80 the box. The end flaps 2 are then turned upwardly against theend `Iiaps 5 to complete the folding of the blank. It lis* to be noted that When the box is set up it has a double thicknessI of material at the corners. ,.855 I n packing a stack of paper cards, indi` 5, the stack'is laid upon the base 1 and a sheet of stiff paperboard c, of corresponding length and Width, is laidV uponjthe stack. The height of the stack 9 plus the thickness ofthis board is just sufficient to fill the box. A eoatingof adhesive substance, such as silicate of soda., is then applied to the top of the board e and the' sides and top 'portions'of the box are then 95 folded over the stack (l and board. e, in themanner heretofore described.` The top portions are thus brought into contact With'the coated surface of the board e-and they be- Whenthe lio . tended only over the top Wardly between coating dries. After folding hthe top and side portions of the box, a sealing strip f, which may be a strip of tough paper ing an adhesive coating on one side, is laid along the central longitudinal part of the box and cemented to the box, and the ends f of the strip are extended downwardly on the end flaps 5 of the cover portion, as shown in Figs. 1, 2 and 3.l The meeting edges 4a of the cover portion and the meeting edges 5a of the flaps 5 are thus covered and seaIed by the strip. A coating of strong adhesive material, such as silicate of soda, is then applied to the end flaps 2 of the base portion-and these are turned upwardly against the flaps 5 and the ends f of the sealing strip. Pressure is applied to the top andv ends of the box until the adhesive has dried. The board e reinforces the top of the box and being adhesively without destroying the top of the box. Similarly, the end flaps 5, being adhesively secured to the {iaps 2, cannot be opened ex cept by mutilation of the box ends. sealing strip f is provided in order to detect tampering with the box.` I'f the strip exportion Aof the box, it might be yremoved and replaced by another strip, without detection, but by extending the ends of the sealing strip downthe flaps 2 and 5 and by cementing these flaps together, it becomes impossible'to remove and replace. the entire strip, and if thestrip is not continuous with its ends sealed in, when the box arrives at its destination, .it will be evident that an attempt has been made to open the box.

Where the box is4 used for shippingl articles which are not likely to be stolen and where it is not important to detect tampering with the box, the ends of the sealing strip may be brought down on the outer sides of the ends of the box and cemented to its ends, as shown in Figy.
